  • Patent number: 8991222
    Abstract: Disclosed herein is a washing machine that is capable of increasing a frictional force between an outer diameter of a rotary shaft and an inner race of a bearing to prevent the sliding between the rotary shaft and the bearing due to a gap between the outer diameter of the rotary shaft and the inner race of the bearing, thereby preventing creep noise from the rotary shaft. The washing machine includes at least one elastic member disposed between the outer diameter of the rotary shaft and the inner race of the bearing to prevent noise due to the sliding between the rotary shaft and the bearing.

  • Patent number: 8984917
    Abstract: A washing machine in accordance with the present invention includes a mounting member disposed between a stator and a bearing housing. Thus, when a motor is rotated according to an operation of the washing machine, the transmission of vibration, which is generated by a repulsive force of the stator, to the bearing housing can be reduced efficiently. Accordingly, a tub coupled to the bearing housing can be prevented from vibrating due to the vibration of the stator, and noise due to the vibration of the tub can be reduced.

    Abstract: An exemplary washing machine appliance includes a cabinet, a tub positioned within the cabinet, a drum rotatably mounted within the tub, a balancing apparatus configured to offset an imbalance created by articles in the drum, and a motor in mechanical communication with the drum. The motor is configured for selectively rotating the drum within the tub. The washing machine appliance includes a controller configured to perform operations. The operations include receiving a signal indicative of a speed of the motor. The operations include determining a deviation of the speed of the motor from a target motor speed and comparing the deviation to one or more threshold values. The operations include determining whether to perform a rebalancing process or a spin out process based on the comparison of the deviation to the one or more threshold values.
